The inside lock body 1 further includes a first plate 114 that protects the components disposed in the accommodating space 112 and that is screwed to the inside housing 11 by screws 100, and a second plate 115 that covers at least part of an opening of the accommodating space 112.
The latch unit 2 in this embodiment is a deadbolt latch mechanism and includes a housing 21, a latch drive 22 having a tailpiece through hole 23, and a latch 24 driven by the latch drive 22 to switch between an unlatched position (see Figure 5) and a latched position (see Figure 6) . The latch 24 is not visible in Figure 5 since the latch 24 is retracted into the housing 21 in the unlatched position.
The outside lock body 3 includes an outside housing 31, a lock body 32, a tailpiece 33 and an electronic operation module 34. The electronic operation module 34 is a set of buttons in this embodiment. Alternatively, the electronic operation module 34 may be a fingerprint recognition device, a remote control device, touch panel, etc. The electronic operation module 34 is electrically connected to the control unit 17. The tailpiece 33 is connected to the lock body 32, extends through the tailpiece through hole 23 of the latch drive 22, and is inserted into the slot 123 of the shaft portion 122 of the rotary handle 12. The tailpiece 33 lies horizontally in the slot 123 in Fig. 1.
When the user twists the rotary handle 12, the tailpiece 33 co-rotates with the rotary handle 12, and operates the latch drive 22 so that the latch 24 is driven to move between the latched position and the unlatched position. When the user operates the electronic door lock 4 with the outside lock body 3 (i.e., using the electronic operation module 34) , the transmission wheel 15 is driven to rotate by the
13 driving device 13, and the driving elements 154 of the transmission wheel 15 respectively push and drive the tongues 1614 of the rotational actuator 16 so that the rotational actuator 16 rotates together with the transmission wheel 15 and the rotary handle 12. As a result, the latch 24 moves between the latched and unlatched positions.
Further referring to Figures 5 to 7, when the electronic door lock 4 is mounted on a right-handed door (DR) having an openable right side (SR) , a method for correctly mounting the electronic door lock 4 on the right-handed door (DR) is implemented as follows.
First, the outside lock body 3 and the latch unit 2 of the electronic door lock 4 are assembled on the right-handed door (DR) . At this time, the tailpiece 33 lies horizontally in the tailpiece through hole 23, and the latch 24 is proximal to the openable right side (SR) of the right-handed door (DR) and is at the unlatched position as shown in Figure 5. Bymanually rotating the rotary handle 12, the protrusion 1624 of the rotational actuator 16 is initially placed in the first angular position so that the protrusion 1624 presses the first switch 171. Then, the inside lock body 1 of the electronic door lock 4 is mounted on the right-handed door (DR) , the first switch 171 is placed proximally to the openable right side (SR) of the right-handed door (DR) , and the tailpiece 33 is inserted horizontally into the slot 123.

Further referring to Figures 5 to 7, when the electronic door lock 4 is mounted on a right-handed door (DR) having an openable right side (SR) , a method for correctly mounting the electronic door lock 4 on the right-handed door (DR) is implemented as follows.
First, the outside lock body 3 and the latch unit 2 of the electronic door lock 4 are assembled on the right-handed door (DR) . At this time, the tailpiece 33 lies horizontally in the tailpiece through hole 23, and the latch 24 is proximal to the openable right side (SR) of the right-handed door (DR) and is at the unlatched position as shown in Figure 5. Bymanually rotating the rotary handle 12, the protrusion 1624 of the rotational actuator 16 is initially placed in the first angular position so that the protrusion 1624 presses the first switch 171. Then, the inside lock body 1 of the electronic door lock 4 is mounted on the right-handed door (DR) , the first switch 171 is placed proximally to the openable right side (SR) of the right-handed door (DR) , and the tailpiece 33 is inserted horizontally into the slot 123.
After the electronic door lock 4 is assembled on the right-handed door (DR) , the electronic door lock 4 is
14 electrically energized such that the control unit 17 automatically implements an operating procedure for determining a correct mounting direction of the electronic door lock 4. The operating procedure includes the following steps R1 to R5.
In step R1, when the protrusion 1624 is initially placed at the first angular position to generate the first signal and when the latch 24 is initially placed at the unlatched position, the control unit 17 detects that the first switch is pressed by the protrusion 1624, and controls the driving device 13 of the driving unit 10, in response to receipt of the first signal, to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a first direction from the first switch 171 that is initially pressed to the second switch 172 that is initially un-pressed (i. e. , the direction (A) in Figure 5) , and for driving the latch 24 to move from the unlatched position toward the latched position.
In step R2, when the latch 24 is moved to the latched position and when the protrusion 1624 is rotated to the second angular position where the protrusion 1624 presses the second switch 172 that is initially un-pressed to send the second signal, the control unit 17 stops the driving unit 10 in response to receipt of the second signal. During rotating from the first angular position to the second angular position, the protrusion 1624 moves to and presses the second switch 172 after leaving and releasing the first switch 171.
In step R3, after step R2, the control unit 17 controls the driving device 13 of the driving unit 10 to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a second direction from the second switch 172 5 that is initially un-pressed to the first switch 171 that is initially pressed (i.e., the direction (B) in Figure 7 opposite to the direction (A) in Figure 5) , and for driving the latch 24 to move from the latched position toward the unlatched position.
10 In step R4, when the latch 24 is moved to the unlatched position and when the protrusion 1624 is rotated once again to the first angular position where the first switch 171 is pressed to send the first signal, the control unit 17 stops the driving unit 10 in response to receipt of the first
In step R1, when the protrusion 1624 is initially placed at the first angular position to generate the first signal and when the latch 24 is initially placed at the unlatched position, the control unit 17 detects that the first switch is pressed by the protrusion 1624, and controls the driving device 13 of the driving unit 10, in response to receipt of the first signal, to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a first direction from the first switch 171 that is initially pressed to the second switch 172 that is initially un-pressed (i. e. , the direction (A) in Figure 5) , and for driving the latch 24 to move from the unlatched position toward the latched position.
In step R2, when the latch 24 is moved to the latched position and when the protrusion 1624 is rotated to the second angular position where the protrusion 1624 presses the second switch 172 that is initially un-pressed to send the second signal, the control unit 17 stops the driving unit 10 in response to receipt of the second signal. During rotating from the first angular position to the second angular position, the protrusion 1624 moves to and presses the second switch 172 after leaving and releasing the first switch 171.
In step R3, after step R2, the control unit 17 controls the driving device 13 of the driving unit 10 to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a second direction from the second switch 172 5 that is initially un-pressed to the first switch 171 that is initially pressed (i.e., the direction (B) in Figure 7 opposite to the direction (A) in Figure 5) , and for driving the latch 24 to move from the latched position toward the unlatched position.
10 In step R4, when the latch 24 is moved to the unlatched position and when the protrusion 1624 is rotated once again to the first angular position where the first switch 171 is pressed to send the first signal, the control unit 17 stops the driving unit 10 in response to receipt of the first
15 signal.
In step R5, the control unit 17 confirms that the electronic door lock 4 is mounted to the right-handed door (DR) with a correct mounting direction when steps R1 to R4 are successfully implemented. Otherwise, the control unit 17 will further implements the step of outputting a warning signal informing that the electronic door lock 4 should be disassembled from the right-handed door (DR) for re-mounting.
For example, in order to re-mount the electronic door lock 4, the inside lock body 1 is disassembled from the door, so that the rotational actuator 16 can be adjusted for placing the protrusion 1624 correctly in the first angular position by manually rotating the rotary handle 12.
In step R5, the control unit 17 confirms that the electronic door lock 4 is mounted to the right-handed door (DR) with a correct mounting direction when steps R1 to R4 are successfully implemented. Otherwise, the control unit 17 will further implements the step of outputting a warning signal informing that the electronic door lock 4 should be disassembled from the right-handed door (DR) for re-mounting.
For example, in order to re-mount the electronic door lock 4, the inside lock body 1 is disassembled from the door, so that the rotational actuator 16 can be adjusted for placing the protrusion 1624 correctly in the first angular position by manually rotating the rotary handle 12.
16 In this embodiment, the warning signal is outputted when step R2 is not implemented after step R1, when the control unit 17 fails to receive the second signal after the driving unit 10 operates for a predetermined length of time (e.g., 3 seconds) in step R1, or when the control unit 17 fails to receive the first signal after the driving unit 10 operates for the predetermined length of time in step R3. In this condition, the inside lock body 1 should be disassembled from the door, and the rotational actuator 16 should be adjusted by manually rotating the rotary handle 12. After the inside lock body 1 is re-mounted to the door, steps R1 to R5 may be repeated for re-confirmation.
After the electronic door lock 4 is successfully mounted to the right-handed door (DR) , as shown in Figure 5, the latch 24 is in the unlatched position when the protrusion 1624 of the rotational actuator 16 presses the first switch 171. The pressing of the first switch 171 is able to inform the control unit 17 that the latch is currently at the unlatched position. At this time, the driving element 154 at the upper side of the transmission wheel 15 is situated at the right side in Figure 5. If the user operates the electronic operation module 34 for unlocking the electronic door lock 4 (or unlatching the latch 24) in this condition, an error warning output will be generated.
When the user wants to lock the electronic door lock 4 using the rotary handle 12, the user may manually twist the rotary handle 12 to drive the rotational actuator 16 to rotate
After the electronic door lock 4 is successfully mounted to the right-handed door (DR) , as shown in Figure 5, the latch 24 is in the unlatched position when the protrusion 1624 of the rotational actuator 16 presses the first switch 171. The pressing of the first switch 171 is able to inform the control unit 17 that the latch is currently at the unlatched position. At this time, the driving element 154 at the upper side of the transmission wheel 15 is situated at the right side in Figure 5. If the user operates the electronic operation module 34 for unlocking the electronic door lock 4 (or unlatching the latch 24) in this condition, an error warning output will be generated.
When the user wants to lock the electronic door lock 4 using the rotary handle 12, the user may manually twist the rotary handle 12 to drive the rotational actuator 16 to rotate
17 in the direction (A) . Since the rotary handle 12, the tailpiece 33 and the rotational actuator 16 are co-rotatable, the tailpiece 33 drives the latch drive 22 to move the latch 24 from the unlatched position toward the latched position when the user twists the rotary handle 12. In the meanwhile, as shown in Figure 6, the protrusion 1624 of the rotational actuator 16 moves to the second angular position and presses the second switch 172. The pressing of the second switch 172 is able to inform the control unit 17 that the latch is currently at the latched position. If the user operates the electronic operation module 34 for locking the electronic door lock 4 (or for latching the latch 24) in this condition, an error warning output is generated. When the user wants to unlock the electronic door lock 4 using the rotary handle 12, the user may twist the rotary handle 12 in the direction (B) opposite to the direction (A) . Similarly, the lock body 32 of the outside lock body 3 can be manually operated with a particular key to achieve the same function.
When the user wants to lock the electronic door lock 4 using the electronic operation module 34, the user may operate the electronic operation module 34 (e.g., by inputting a password) to send a locking signal to the control unit 17. In response to receipt of the locking signal, the control unit 17 controls the driving device (motor) 13 to rotate the worm shaft 132. As a result, the worm shaft 132 drives rotation of the driving wheel 14 which in turn drives the transmission wheel 15 to rotate in the direction (A) ,
When the user wants to lock the electronic door lock 4 using the electronic operation module 34, the user may operate the electronic operation module 34 (e.g., by inputting a password) to send a locking signal to the control unit 17. In response to receipt of the locking signal, the control unit 17 controls the driving device (motor) 13 to rotate the worm shaft 132. As a result, the worm shaft 132 drives rotation of the driving wheel 14 which in turn drives the transmission wheel 15 to rotate in the direction (A) ,
18 so that the driving elements 154 of the transmission wheel 15 move respectively toward the tongues 1614 of the rotational actuator 16, and push and drive the same.
Therefore, the rotational actuator 16 rotates in the direction (A) , and the protrusion 1624 moves to the second angular position as shown in Figure 6. At this time, the rotational actuator 16 is unable to rotate further in the direction (A) since the latch 24 is at the latched position.
However, as the driving device 13 is still rotatable for a predetermine time period to drive the transmission wheel to further rotate, the driving elements 154 are slidable respectively over the rounded outer surfaces of the tongues 1614 as shown in Figure 7. As a result, the driving elements 154 will not interfere with the tongues 1614 when the user 15 manually. operates the rotary handle 12 to rotate the rotational actuator 16 in the direction (B) for unlocking the electronic door lock 4. When the user wants to unlock the electronic door lock 4 using electronic operation module 34, the operation sequence and rotation direction are just inverse, and details thereof are omitted herein for the sake of brevity.
Referring to Figures 1 and 8 to 10, when the electronic door lock 4 is mounted on a left-handed door (DL) having an openable left side (SL) , a method for correctly mounting the electronic door lock 4 on the left-handed door (DL) is implemented as follows.
First, the outside lock body 3 and the latch unit 2 of
Therefore, the rotational actuator 16 rotates in the direction (A) , and the protrusion 1624 moves to the second angular position as shown in Figure 6. At this time, the rotational actuator 16 is unable to rotate further in the direction (A) since the latch 24 is at the latched position.
However, as the driving device 13 is still rotatable for a predetermine time period to drive the transmission wheel to further rotate, the driving elements 154 are slidable respectively over the rounded outer surfaces of the tongues 1614 as shown in Figure 7. As a result, the driving elements 154 will not interfere with the tongues 1614 when the user 15 manually. operates the rotary handle 12 to rotate the rotational actuator 16 in the direction (B) for unlocking the electronic door lock 4. When the user wants to unlock the electronic door lock 4 using electronic operation module 34, the operation sequence and rotation direction are just inverse, and details thereof are omitted herein for the sake of brevity.
Referring to Figures 1 and 8 to 10, when the electronic door lock 4 is mounted on a left-handed door (DL) having an openable left side (SL) , a method for correctly mounting the electronic door lock 4 on the left-handed door (DL) is implemented as follows.
First, the outside lock body 3 and the latch unit 2 of
19 the electronic door lock 4 are assembled on the left-handed door (DL) . At this time, the tailpiece 33 lies horizontally in the tailpiece through hole 23, and the latch 24 is proximal to the openable left side (SL) of the left-handed door (DL) and is at the unlatched position, as shown in Figure 8.
Thereafter, the rotary handle 12 is rotated manually to initially place the protrusion 1624 of the rotational actuator 16 in the second angular position where the protrusion 1624 presses the second switch 172. Then, the inside lock body 1 of the electronic door lock 4 is mounted on the left-handed door (DL) , the second switch 172 is placed proximally to the openable left side (SL) of the left-handed door (DL) , and the tailpiece 33 is inserted horizontally into the slot 123. After the electronic door lock 4 is assembled on the left-handed door (DL) , the electronic door lock 4 is electrically energized such that the control unit 17 automatically implements an operating procedure for determining a correct mounting direction of the electronic door lock 4. The operating procedure includes the following steps Li to L5.
In step Li, when the protrusion 1624 is initially placed at the second angular position to generate the second signal and when the latch 24 is initially placed at the unlatched position, the control unit 17 controls the driving device 13 of the driving unit 10, in response to receipt of the second signal, to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a first direction from the second switch 172 that is initially pressed to the first switch 171 that is initially un-pressed (i.e., the direction (B) in Figure 8), and for driving the latch 24 to move from the unlatched position toward the latched 5 position.
In step L2, when the latch 24 is moved to the latched position and when the protrusion 1624 is rotated to the first angular position where the protrusion 1624 presses the first switch 171 that is initially un-pressed to send the first 10 signal, the control unit 17 stops the driving unit 10 in response to receipt of the first signal. In particular, during rotating from the second angular position to the first angular position, the protrusion 1624 moves to and presses the first switch 171 after leaving and releasing the second 15 switch 172.
In step L3, after step L2, the control unit 17 controls the driving device 13 of the driving unit 10 to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a second direction from the first switch 171
Thereafter, the rotary handle 12 is rotated manually to initially place the protrusion 1624 of the rotational actuator 16 in the second angular position where the protrusion 1624 presses the second switch 172. Then, the inside lock body 1 of the electronic door lock 4 is mounted on the left-handed door (DL) , the second switch 172 is placed proximally to the openable left side (SL) of the left-handed door (DL) , and the tailpiece 33 is inserted horizontally into the slot 123. After the electronic door lock 4 is assembled on the left-handed door (DL) , the electronic door lock 4 is electrically energized such that the control unit 17 automatically implements an operating procedure for determining a correct mounting direction of the electronic door lock 4. The operating procedure includes the following steps Li to L5.
In step Li, when the protrusion 1624 is initially placed at the second angular position to generate the second signal and when the latch 24 is initially placed at the unlatched position, the control unit 17 controls the driving device 13 of the driving unit 10, in response to receipt of the second signal, to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a first direction from the second switch 172 that is initially pressed to the first switch 171 that is initially un-pressed (i.e., the direction (B) in Figure 8), and for driving the latch 24 to move from the unlatched position toward the latched 5 position.
In step L2, when the latch 24 is moved to the latched position and when the protrusion 1624 is rotated to the first angular position where the protrusion 1624 presses the first switch 171 that is initially un-pressed to send the first 10 signal, the control unit 17 stops the driving unit 10 in response to receipt of the first signal. In particular, during rotating from the second angular position to the first angular position, the protrusion 1624 moves to and presses the first switch 171 after leaving and releasing the second 15 switch 172.
In step L3, after step L2, the control unit 17 controls the driving device 13 of the driving unit 10 to operate for driving the rotational actuator 16 and the protrusion 1624 to rotate in a second direction from the first switch 171
20 that is initially un-pressed to the second switch 172 that is initially pressed (i.e., the direction (A) in Figure 10 opposite to the direction (B) in Figure 8), and for driving the latch 24 to move from the latched position toward the unlatched position.
In step L4, when the latch 24 is moved to the unlatched position and when the protrusion 1624 is rotated to the second angular position, the second switch 172 is pressed to send
In step L4, when the latch 24 is moved to the unlatched position and when the protrusion 1624 is rotated to the second angular position, the second switch 172 is pressed to send
21 the second signal, and the control unit 17 stops the driving unit 10 in response to receipt of the second signal.
In step L5, the control unit 17 confirms that the electronic door lock 4 is mounted to the left-handed door (DL) with a correct mounting direction when steps Li to L4 are successfully implemented. Otherwise, the control unit 17 will further implement the step of outputting the warning signal informing that the electronic door lock 4 should be disassembled from the left-handed door (DL) for re-mounting.
In this embodiment, the warning signal is outputted when step L2 is not implemented after step Li, when the control unit 17 fails to receive the first signal after the driving unit 10 operates for the predetermined length of time in step Li, or when the control unit 17 fails to receive the second signal after the driving unit 10 operates for the predetermined length of time in step L3. In this condition, the inside lock body 1 should be disassembled from the door, and the rotational actuator 16 should be adjusted by manually rotating the rotary handle 12. In order to re-mount the electronic door lock 4, the inside lock body 1 is disassembled from the door, so that the rotational actuator 16 can be adjusted for placing the protrusion 1624 correctly in the second angular position by manually rotating the rotary handle 12. After the inside lock body 1 is re-mounted to the door, steps Li to L5 may be repeated.
After the electronic door lock 4 is successfully mounted to the left-handed door (DL) , as shown in Figure 8, the
In step L5, the control unit 17 confirms that the electronic door lock 4 is mounted to the left-handed door (DL) with a correct mounting direction when steps Li to L4 are successfully implemented. Otherwise, the control unit 17 will further implement the step of outputting the warning signal informing that the electronic door lock 4 should be disassembled from the left-handed door (DL) for re-mounting.
In this embodiment, the warning signal is outputted when step L2 is not implemented after step Li, when the control unit 17 fails to receive the first signal after the driving unit 10 operates for the predetermined length of time in step Li, or when the control unit 17 fails to receive the second signal after the driving unit 10 operates for the predetermined length of time in step L3. In this condition, the inside lock body 1 should be disassembled from the door, and the rotational actuator 16 should be adjusted by manually rotating the rotary handle 12. In order to re-mount the electronic door lock 4, the inside lock body 1 is disassembled from the door, so that the rotational actuator 16 can be adjusted for placing the protrusion 1624 correctly in the second angular position by manually rotating the rotary handle 12. After the inside lock body 1 is re-mounted to the door, steps Li to L5 may be repeated.
After the electronic door lock 4 is successfully mounted to the left-handed door (DL) , as shown in Figure 8, the
22 protrusion 1624 of the rotational actuator 16 presses the second switch 172, so that the second switch 172 sends the second signal to the control unit 17 to inform the control unit 17 that the protrusion 1624 is placed at the second angular position corresponding to the unlatched position of the latch 24. On the other hand, when the protrusion 1624 is at the first angular position as shown in Figure 9, the protrusion 1624 presses the first switch 171, so that the first switch 171 sends the first signal to the control unit 17 to inform the control unit 17 that the protrusion 1624 is placed at the first angular position corresponding to the latched position of the latch 24. The operation for locking and unlocking the electronic door lock 4 mounted on the left-handed door (DL) is similar to the operation of the electronic door lock 4 mounted to the right-handed door, and details thereof will be omitted herein for the sake of brevity.
It is worth mentioning that the control unit 17 is able to generate a warning signal and to control at the same time the driving unit 10 to stop from rotating if the first switch 171 or the second switch 172 is not pressed by the protrusion 1624 after the driving unit 10 has rotated for a predetermined time period, for example, 3 seconds.
In sum, the method for correctly mounting the electronic door lock 4 on a left-handed or right-handed door according to the embodiment of this disclosure can facilitate correct installation of the electronic door lock 4, and can inform
